Studies on identification of menstrual blood stain by fibrin-plate method. II. A study on the identification of menstrual blood stain

The fibrinolytic activity of plasmin present in menstrual blood has been studied by means of the Fibrin-Plate Method, and utilizing the findings of such a study, the identification of menstrual blood stain in legal medicine has been conducted. As the result, it has become clear that the identification of a very small amount of menstrual blood is possible, for an example, only one thread from the menstrual blood stained cloth 1.0 cm2. in size, and with the blood stain left in a room temperature for as long as two years, or with the blood stain left in water for one month, it is possible to identify menstrual blood. Aside from menstrual blood, no other toco-gynecological blood responds to this Fibrin-Plate Method.
